Patent mapping

ABSTRACT

A system and computer implemented method are provided. The method comprises maintaining a database of patent portfolios and a database of patents, with each patent stored in the database of patents being associated with one or more patent portfolios stored in the database of patent portfolios. The method includes receiving a search query associated with a first patent portfolio; searching the first portfolio as a function of the search query; generating a seed set of search results including one or more patent claims associated with the search query, the patent claims including terms from the search query; automatically generating an expanded set of search results including one or more patent claims further associated with the search query or associated with the patent claims in the seed set of search results; and mapping the one or more patent claims to a patent concept.

BACKGROUND

The management of a patent portfolio involves multiple stages. Initially, a decision is made as to what inventions are worth the investment of filing a patent application. Then, each filed patent application goes through prosecution with the patent office. Finally, for each patent that is allowed, maintenance fees are usually payable at a variety of intervals to keep the patent in force. Quick claim scope or relevancy determination is important in managing the assessment of large volumes of patent matters in a patent portfolio.

Tools for identifying patents for a particular purpose such as a prior art search, validity analysis, or a freedom to operate investigation, operate by performing Boolean queries using various search operators. These operators allow for searching by date, terms, document number, and patent classification, among others. These tools further allow for searching individual document portions such as a document title, abstract, or claim set.

Other searching tools accept freeform text. Such tools accept a freeform text block and extract information from the text block deemed most likely to return acceptable results. However, such tools are still limited to only performing Boolean queries and displaying a list of results.

These search tools often provide large numbers of results, most of which are irrelevant. These tools fail to present results in a manner allowing for quick relevancy determinations. The presentation also fails to provide enough detail suggesting how to adjust a search for obtaining only relevant results. Further, the search tools provide the documents of the result set in a manner very similar to the traditional paper format of the documents. Quick relevancy determination is important in managing the assessment of large volumes of prior art for potential citation to government patent agencies.

DETAILED DESCRIPTION

The life cycle of a patent may include multiple stages. These stages generally include invention, filing a patent application on the invention, prosecuting the patenting application to allowance or abandonment, determining whether to file any continuing applications, and paying maintenance fees on the allowed patent.

At each stage, one or more parties determine the best course of action to take with respect to the invention. For example, when determining whether or not to file a patent, the inventor may know what products are out in the technology area of the invention, a business manager may know how the invention fits in with a company's goals, and a patent attorney may have researched existing patents or application in the technology area of the patent. These parties will ultimately decide whether it is worth the initial investment of filing an application on the invention and then determine the next course of action at each future stage.

In some instances, an inventor, business manager or portfolio manager may wish to monitor the patent activities of one or more competitors. The provision of up-to-date information relating to cited references or technology trends in the art to which a user's or competitor's patent portfolio relates may be particularly helpful in devising patenting strategy or making informed business decisions.

Tools

In various embodiments, a patent management system includes tools to help the parties involved in the patenting process make decisions at each stage in the life of a patent. These tools may also be used for general research by parties not immediately involved with the patenting of the invention. Additionally, these tools may be used as standalone tools, in combination with other tools, and in combination with other patent management systems. Examples of tools include, but are not limited to, prosecution analytics, reference management, prior art analytics, docketing management, claim mapping, claim analytics, portfolio analytics, external database (e.g., PAIR) analytics, annuity management, and strategic monitoring.

Meaning of Certain Terms

The systems, methods and tools of the present disclosure set forth in this specification are described in relation to a patent management system and patent matters, but it will be understood that embodiments of the present invention could equally be applied to other forms of intellectual property (trademarks, copyright, registered designs, and the like). Moreover, the term “patent” is not intended to be limited to an issued patent, but may include a pending patent application or un-filed application or invention disclosure. The term “user” is intended to cover any person interacting with the patent management system. A user may be an inventor, portfolio manager, business manager or patent attorney, for example.

Computer Network System

FIG. 1 is a schematic view of computer network system 100 according to various embodiments. The computer network system 100 includes patent management system 102 and user terminal 104 communicatively coupled via network 106. In an embodiment, patent management system 102 includes web server 108, application server 110, and database management server 114, which may be used to manage at least operations database 116 and file server 118. Patent management system 102 may be implemented as a distributed system; for example, one or more elements of the patent management system 102 may be located across a wide-area network (WAN) from other elements of patent management system 102. As another example, a server (e.g., web server 108, file server 118, database management server 114) may represent a group of two or more servers, cooperating with each other, provided by way of a pooled, distributed, or redundant computing model.

Network

Network 106 may include local-area networks (LAN), wide-area networks (WAN), wireless networks (e.g., 802.11 or cellular network), the Public Switched Telephone Network (PSTN) network, ad hoc networks, personal area networks (e.g., Bluetooth) or other combinations or permutations of network protocols and network types. The network 106 may include a single local area network (LAN) or wide-area network (WAN), or combinations of LAN's or WAN' s, such as the Internet. The various devices/systems coupled to network 106 may be coupled to network 106 via one or more wired or wireless connections.

Web Server

Web server 108 may communicate with file server 118 to publish or serve files stored on file server 118. Web server 108 may also communicate or interface with the application server 110 to enable web-based applications and presentation of information. For example, application server 110 may consist of scripts, applications, or library files that provide primary or auxiliary functionality to web server 108 (e.g., multimedia, file transfer, or dynamic interface functions). Applications may include code, which when executed by one or more processors, run the tools of patent management system 102. In addition, application server 110 may also provide some or the entire interface for web server 108 to communicate with one or more of the other servers in patent management system 102 (e.g., database management server 114).

Web server 108, either alone or in conjunction with one or more other computers in patent management system 102, may provide a user-interface to user terminal 104 for interacting with the tools of patent management system 102 stored in application server 110. The user-interface may be implemented using a variety of programming languages or programming methods, such as HTML (HyperText Markup Language), VBScript (Visual Basic® Scripting Edition), JavaScript™, XML® (Extensible Markup Language), XSLT™ (Extensible Stylesheet Language Transformations), AJAX (Asynchronous JavaScript and XML), Java™, JFC (Java™ Foundation Classes), and Swing (an Application Programming Interface for Java™)

User Terminal

User terminal 104 may be a personal computer or mobile device. In an embodiment, user terminal 104 includes a client program to interface with patent management system 102. The client program may include commercial software, custom software, open source software, freeware, shareware, or other types of software packages. In an embodiment, the client program includes a thin client designed to provide query and data manipulation tools for a user of user terminal 104. The client program may interact with a server program hosted by, for example, application server 110. Additionally, the client program may interface with database management server 114.

Operations Database

Operations database 116 may be composed of one or more logical or physical databases. For example, operations database 116 may be viewed as a system of databases that when viewed as a compilation, represent an “operations database.” Sub-databases in such a configuration may include a matter database, a portfolio database, a user database, a mapping database and an analytics database. Operations database 116 may be implemented as a relational database, a centralized database, a distributed database, an object oriented database, or a flat database in various embodiments.

Framework, Data structure and Sources

In various embodiments, the tools of the patent management system 102 share a common framework. The framework may have a base organization unit of a matter. In various embodiments, a matter is an issued patent or patent application that includes one or more patent claims. In an embodiment, a matter is generally identified by its patent number or publication number. Identification may mean either identification as it relates to a user of the patent management system 102 or within the patent management system 102. Thus, a user may see a matter listed as its patent number while internally a database of the patent management system 102 may identify it by a random number. One or more matters may be associated with prior art or cited references stored in a reference or prior art database.

One or more matters may be grouped together to form a portfolio. A matter may also be associated with one or more other matters in a family. A family member may be a priority matter, a continuing (e.g., continuation, divisional) matter, or foreign counter-part member. Family members may be determined according to a legal status database such as INPADOC.

Data stored in a first database may be associated with data in a second database through the use of common data fields. For example, consider entries in the matter database formatted as [Matter ID, Patent Number] and entries in the portfolio database formatted as [Portfolio ID, Matter ID]. In this manner, a portfolio entry in the portfolio database is associated with a matter in the matter database through the Matter ID data field. In various embodiments, a matter may be associated with more than one portfolio by creating multiple entries in the portfolio database, one for each portfolio that the matter is associated with. In other embodiments, one or more patent reference documents may be associated with a patent by creating multiple entries in the patent database, for example. The structure of the database and format and data field titles are for illustration purposes, and other structures, names, or formats may be used. Additionally, further associations between data stored in the databases may be created as discussed further herein.

During operation of patent management system 102, data from multiple data sources (internal and external) is imported into or accessed by the operations database 116. Internal sources may include data from the various tools of the patent management system 102. External sources 120 may include websites or databases associated with foreign and domestic patent offices, assignment databases, WIPO, and INPADOC. In various embodiments, the data is scraped and parsed from the websites if it is unavailable through a database. The data may be gathered using API calls to the sources when available. The data may be imported and stored in the operations database on a scheduled basis, such as daily, weekly, monthly, quarterly, or some other regular or periodic interval. Alternatively, the data may be imported on-demand. The imported data may relate to any information pertaining to patents or patent applications, such as serial numbers, title, cited art, inventor or assignee details and the like.

After data importation, the data may be standardized into a common format. For example, database records from internal or external sources may not be in a compatible format with the operations database. Data conditioning may include data rearrangement, normalization, filtering (e.g., removing duplicates), sorting, binning, or other operations to transform the data into a common format (e.g., using similar date formats and name formats).

Patent Management System—Overview

FIG. 2 is a block diagram of patent management system 102, according to an example embodiment. Illustrated are user database 202, matter database 204, portfolio database 206, mapping database 208, analytics database 210, display module 212, input module 214, mapping module 216, analytics module 218, tracking module 220 and filtering module 222. In various embodiments, the data stored in databases 202, 204, 206, 208, and 210 may be in the same or multiple physical locations. For example, portfolio database 206 may be stored in one or more computers associated with a portfolio management service. In various embodiments, patent management system 102 minors databases stored in other locations. In an embodiment, when a request is made to access data stored in the databases 202-210, patent management system 102 determines where the data is located and directs the request to the appropriate location. Similarly, modules 212-222 may be executed across multiple computer systems.

User Database

In an example embodiment, user database 202 stores data representing users of patent management system 102. The data may include data fields of user credentials including a user ID and password and access rights with respect to patent management system 102. The user ID may be common across the tools of the patent management system 102. In this manner, access rights of the user with respect to the tools of the patent management system 102 may follow across the various tools of the patent management system 102. In an example embodiment, different access rights are granted to a user ID between the various tools.

In various embodiments, each user ID has access rights to one or more matters. Similarly, a user ID may have portfolio level access rights. Access rights may be defined according to at least two parameters: read access and write access. Thus, when a user logs into patent management system 102, the user is presented with access only to the matters/portfolios that have been associated with the user ID. More (e.g., additional contact information) or fewer data fields associated with a user may be included in a user entry stored in user database 202.

Patent or Matter Database

In an embodiment, matter database 204 stores data representing matters. Each matter may be associated with one or more portfolios. In some embodiments, a matter is associated with no portfolios. In various embodiments, a matter is a foreign or domestic patent or application. Matters may also be inventions that have not yet been filed (e.g., as may be the case within a docketing system). In an embodiment, a matter entry includes data fields representing a matter ID, patent number, publication number, serial number, docketing number, title (e.g., the name of the patent or application), type of the matter (e.g., application, issued patent, PCT application), status of the matter (e.g., issued, abandoned, allowed), a link to the patent office where the matter was filed, a link to a PDF download of the matter, abstract of the matter, inventors of the matter, current owner of the matter, cited references on the face of the matter, filed date, issue date, docket number, and annuity information (e.g., due date, country, and amount due). In some embodiments, other patent reference documents or prior art in any form may be stored and associated with one or more matters. More or fewer data fields associated with a patent may be included in a matter entry stored in matter database 204. In an example embodiment, matter database 204 may store a patent matter database, wherein this database includes data about the patent matters. The data may include, for at least one patent matter, a claim set or statement of invention and a priority date for the claim set or statement of invention.

Matter database 204 may also store a database of prior art documents (also known as “references”), wherein the prior art database includes data about the prior art documents. The data may include, for at least one prior art document, a priority date or publication date of the document. One or more of the prior art documents may be associated with a first patent matter in the patent matter database.

Matter database 204 may also store data obtained from internal or external sources relating to cited references owned by or cited against (in “forward” or “reverse” manner) a target entity (for example, a client of a firm) as well as cited references owned by or cited against (in “forward” or “reverse” manner) another entity (for example, a competitor of the client or other target entity). Public bibliographic details of such cited references may be obtainable from websites or databases associated with foreign and domestic patent offices (PAIR), assignment databases, WIPO, and INPADOC. In various embodiments, the data is scraped and parsed from the websites if it is unavailable through a database. The data may be gathered using API calls to the sources when available. The data may be imported and stored in the operations database 116 (of FIG. 1) on a scheduled basis, such as daily, weekly, monthly, quarterly, or some other regular or periodic interval. Alternatively, the data may be imported on-demand. The imported data may relate to any information pertaining to patents or patent applications, such as serial numbers, title, cited art, inventor or assignee details and the like.

In various embodiments, a matter is associated with one or more other matters as a family with a family ID. Family members may be priority documents, continuation patents/applications, divisional patents/applications, and foreign patent/application counterparts. In an embodiment, family information is determined according to an external source such as INPADOC. Patent reference documents and/or other prior art may be manually or automatically stored, cross-cited and associated with related family matters, for example.

Portfolio Database

Portfolio database 206, in an example embodiment, stores data representing portfolios of one or more matters. Data stored in portfolio database 206 may have been previously generated by a tool of patent management system 102. In various embodiments, a portfolio may be generated by a user using patent management system 102. For example, a user interface may be presented to the user requesting a name for the portfolio and identifiers of matters to be included in the portfolio. In an embodiment, a portfolio entry in portfolio database 206 includes the data fields of portfolio ID and portfolio name. Additionally, a data field for matter ID may also be included in an entry in the portfolio database 206. Thus, each portfolio may be associated with one or more matters through the use of the matter ID data field. More or fewer data fields associated with a portfolio may be included in a portfolio entry of portfolio database 206.

Mapping Database and Patent Concepts

In various embodiments, mapping database 208 may include mappings of patent concepts to one or more matters. In an example embodiment, the underlying patents and patent claims included in each patent portfolio may be categorized by patent concepts (sometimes referred to herein as concepts) such as scope concepts (SC) and technology categories (TC).

In an example embodiment, technology categories are categories that claims relate to, but are not necessarily limited to. For example, a claim to a pulse generator may be put in the technology category “pacemaker”, but not be limited to a pacemaker per se—perhaps the claim merely says that the pulse generator generates a pulse of certain type that is useful for pacing, but pacing does not appear in the claim. Hence, the claim relates to the technology category “pacemaker,” but it is not limited to being a pacemaker.

In an example embodiment, scope concepts are concepts that a claim is limited to. This is in contrast to technology categories, where the claim may be mapped to a TC but it not necessarily limited to it. A scope concept may be defined in a way to give the concept a context that a user can understand without necessarily having to look at the corresponding claim language. For example, if the scope concept is “method or apparatus for cardiac rhythm management”, and it is mapped to claim A, then claim A by definition is limited to this application, such that if a target device does not perform cardiac rhythm management, then it would not infringe claim A.

In an example embodiment, there are two types of scope concepts: 1) high level scope concepts that are like technical categories in the sense they are broad and general and apply to many claims in a portfolio; and 2) scope concepts that are specific to a limited number of claims—for example all claims in a patent may be limited to a very specific distinguishing feature, and this feature could be the basis for a scope concept.

In some example embodiments, high level scope concepts may be defined prior to mapping, and then assigned as applicable. For example, several scope concepts like: atrial pacing, ventricular pacing, defibrillation method or device, etc, may be defined. Then a mapping team may go through all claims in a portfolio and map these scope concepts to claims that are limited to these concepts. After the mapping is complete, an analysis may be done showing how many claims in the portfolio are limited to each of these scope concepts, and the claims may be presented for each SC. This may be useful in disqualifying claims that are not of interest to a particular target (e.g., if an analysis is being done to find a claim that covers an alleged infringer).

In some example embodiments, specific scope concepts are mapped patent by patent or by patent family. These may enable a person to create one or two scope concepts that can be mapped across all claims in a given patent, a family of patents, or across a portion of a patent portfolio. In order to effectively formulate a scope concept that may be globally useful across a patent portfolio, it may be useful to be able to examine multiple patent claims at the same time even if they are not all in the same patent or patent family. A keyword mapping may indicate that there is an exact match between the keyword and a subset of the claim language.

Analytics Database

In various embodiments, analytics database 210 stores data representing calculated analytics on data stored within patent management system 102 or external data sources. In various embodiments, analytics are organized according to an individual matter, a portfolio, or family, or date of an event (such as an assignment recordal, for example). Events may be organized by a date range (for example, all assignments occurring between Corporation A and Corporation B in the last 6 months, or all filings made by inventor X in last 12 months). The calculated analytics may be based on information gathered from multiple sources such as databases of patent management system 102 and PAIR.

In various embodiments, information for an individual matter may include status (e.g., disclosure received, drafting, filed, completed-waiting examination, in prosecution, allowed, issued), cited prior art, list and type of rejections (e.g., 35 U.S.C. §101, 102, 103) number of claims allowed, office action count, interviews held, IDS statements filed, attorney fees to date, and PTO fees to date. Further metrics for an individual matter stored in analytics database 210 may include time waiting for examiner, total time in examination, time waiting for PTO while in examination, and time on appeal. Additional prosecution details may include an upcoming docket date (e.g., due dates for office action, IDS due dates, etc.). A claim prosecution history chart may also be stored in analytics database 210 for each matter. The prosecution history may include a history of claim amendments and arguments made in prosecution.

In various embodiments, portfolio and family analytics information may be stored in analytics database 210 based on aggregating the metrics for an individual matter. In an embodiment, the analytics of a family may differ from those in a portfolio as not all family member matters may be part of a portfolio. Additionally, the analytics may be stored for multiple time periods such that comparisons may be made between current metrics and metrics from a year ago (or other time period).

Aggregated metrics may include total patents and applications, pending and waiting for examination, in prosecution with no claims allowed, in prosecution with some claims allowed, appealed, notice of allowance received, and issued. These metrics may be compiled for both US and international matters in the portfolio. Additional information may include the international portfolio distribution by country. An age distribution of the portfolio may also be compiled. For example the portfolio may be broken down by less than one year old, 1 to 3 years old, 3 to 5 years old, 5 to 10 years old, 10 to 20 years old, and 20 or more years old. Recent filing and issue activity as well as upcoming Ford filing deadlines may be stored in analytics database 210.

In various embodiments, prosecution metrics across a portfolio or family are determined and stored in analytics database 210. This data may include matters waiting for examination, matters in examination, matters appealed, and cases allowed but not yet issued. Analytics with respect to office actions may also be compiled and stored. For example, success of allowance after a first office action response, a second response, and so forth may be stored in analytics database 210. Additional prosecution analytics may include allowance rate (e.g., 10%) after a telephone interview, allowance after an in-person interview, percentage of interviews with response, number and type of rejection, average time in prosecution (e.g., in months), average time to file a response, and average time to next office action. Further, the list of recently allowed cases, recently appealed cases, stalled cases, and recently abandoned cases may also be stored for each portfolio and family in analytics database 210.

In various embodiments, the results of keyword analysis on one or more matters and/or prior art references may be stored in analytics database 210. The keyword analysis may be based on the occurrences of the keywords in the matter or references to derive a score or keyword overlap.

In various embodiments, data stored in the analytics database 210 for a group of matters in a portfolio or family is analyzed to determine the top (e.g., ten) most cited patents, the top most cited inventors, top most cited prior art owners (e.g., according to assignment documents or the face of the patent), newly (e.g., within the last 60 days) cited prior art owners, and top most cited prior art inventors. This information may be stored in analytics database 210.

Display Module

In an embodiment, display module 212 is to display user interfaces and information retrieved from one or more databases 202-210. If a user is accessing patent management system 102 remotely (e.g., through a web browser) display module 212 may be to transmit data representing a user-interface through a network to a user terminal. In various embodiments, display module 212 is to generate one or more charts of data stored in databases 202-210. For example, display module 212 may generate a pie chart of the top 10 inventors within a portfolio.

Input Module

In various embodiments, input module 214 receives data from multiple sources where it may be further processed by one or more other modules and stored in one or more of databases 202-210. In various embodiments, input module 214 or the patent management system 102 may comprise a web server engine or search engine (not shown) for conducting searches through the databases in the system or external thereto, for example at a patent registry or on the Internet. For example, input module 214 may be to utilize one or more APIs to data from one or more patent data stores (e.g., public PAIR, private PAIR, INPADOC, foreign patent offices, patent docketing systems, portfolio management systems, etc). The data may include published patent documents, patent applications, office actions or other patent office correspondence, prior art references, claim mappings, dockets dates, annuity payment data and patent or patent application assignment information. Specific assignment data may include details pertaining to the assignor or assignee (e.g., name, address, nationality, place of incorporation), date of assignment, details of the matter being assigned, or any other data pertaining to assignments or change in ownership that may be recorded at any national or regional patent registry such as the United States Patent and Trademark Office (USPTO), World Intellectual Property Organization (WIPO) or European Patent Office (EPO), for example.

In various embodiments, input module 214 is to receive input from one or more user interface elements. For example, patent management system 102 may present multiple user interfaces to a user. These user interfaces may enable users to input data directly into databases 202-210, instruct the patent management system 102 to retrieve data from patent data stores, and instruct the patent management system to perform various operations (e.g., analysis) on the data in databases 202-210.

Additionally, input module 214 may be to determine the selection of one or more user interface elements by a user and initiate the action associated with the selected user interface element. For example, a user interface element may include a drop-down menu to select a portfolio. Input module 214 may be to receive the selection of the portfolio by the user. Then, input module 214 may pass the selection to one or more other modules for further processing. For example, display module 212 may update the drop-down menu to indicate the selection of the portfolio. In other example embodiments, a user may select an assignee name, or technology field, or date range of potential interest (or a combination of these or other aspects of interest), for which the user wishes to be informed of recent or ongoing assignment or change in ownership status. The user may request to be informed regularly (daily, weekly or monthly, for example) of ongoing assignments or changes in ownership by making a selection of the appropriate interface elements.

In various embodiments, input module 214 processes the data that has been inputted and formats it according to the data fields of databases 202-210 as discussed above. In various embodiments, processing is completed using a parsing module (not shown). For example, consider a patent publication that a user has directed to be inputted into one or more of the databases 202-210. The parsing module may use a combination of automatic image recognition and text analysis to determine the filing date, issue date, title, abstract, and claims of the patent. In some embodiments, the parsing module may flag certain pieces of data that had been determined to be potentially inaccurate (e.g., a number could not be read). A user of patent management system 102 may then examine the flagged data and manually enter the information which is then stored in the appropriate database 202-210.

The resulting data that has been parsed by the parsing module may then be entered as an entry in one or more of databases 202-210. This may be accomplished by, for example, formulating an insert SQL query with the parsed information. In various embodiments, the parsing module may parse multiple pieces of information before generating a database entry. For example, input module 214 may receive a docket number for an issued patent. The docket number may be combined with the information parsed from the issued patent to form an entry in matter database 204.

Mapping and Mining Modules

In various embodiments, mapping module 216 is to facilitate mappings of scope concept, technology categories, prior art and keywords to patent claims of a matter. In an embodiment, mapping signifies association. For example, in conjunction with display module 212, input module 214, or a mining module (not shown), mapping module 216 may present a user interface of patent claims stored in matter database 204 and scope concepts stored in mapping database 208. Input module 214 (or the web server or search engines) may receive a selection of one or more patent claims and one or more scope concepts and pass them to mapping module 216. Mapping module 216 may then formulate an SQL query to associate the one or more patents claims with the one or more scope concepts. When executed, the SQL query may update the mapping database 208 with the associations. In various embodiments, mapping module 216 also allows the creation of new scope concepts, technology categories, and keywords that may be mapped to one or more patent claims. Furthermore, mapping module 216 may present user interfaces that allow a user to rank and rate matters stored in matter database 204.

Mapping module 216 may also allow the generation of claim charts of a plurality of cells. A claim chart may include one or more scope concepts, technology categories, and keywords on one axis and claims of matters in a portfolio on the other axis. The claim chart may include a variety of levels of granularity of scope concepts. Some claims may be mapped to all of the scope concepts while others may not be mapped to any scope concepts. At the cell intersection between a scope concept (or technology category or keyword) and a claim, an indication of the mapping may be presented by changing the format of the cell. For example, the cell may be colored blue when a scope concept is mapped and red when not mapped.

In various embodiments, and as explained in more detail further below, a freedom-to-operate (FTO) analysis can be greatly facilitated using the mapping module 216 to generate claim charts. For example, a series of scope concepts mapped as being present in a claim may themselves be further mapped as being present (or not) in a competitive product. If all the scope concepts in a given claim, representing all the claim elements in that claim, are found present in a product an indication of “likely infringement” can for example be indicated in the claim chart accordingly. Red or green colored cells in a claim chart could, for example, respectively represent instances of when scope concepts are found present (or mapped) in a product, and when not. If the product being assessed was the patentee's own product, a “product coverage” chart could be generated in similar way.

So too a similar approach can be undertaken for validity analysis in which scope concepts are mapped to body of prior art instead of a product, for example. A green colored cell in a “validity” claim chart might indicate a novel concept for example, while a red colored cell might indicate prior disclosure.

In various embodiments, any one or more of the modules 212-222 can be configured to perform patent searches. For example, mapping module 216 may formulate an SQL query to search for one or more keywords or scope concepts in some prior art. The module may be configured to expand the search automatically, for example based on synonyms, forward or reverse citations, or other criteria. In this way, a seed group of patents can be identified and then expanded automatically.

The claim charts referred to above and in further detail below may be termed “Panoramic Claim Charts” in that they quickly provide to a user a panoramic display in summary overview the findings and conclusions of a mapping exercise, whether the analysis be of FTO, product coverage or validity type. For such charts or spreadsheets, further concept organization may be undertaken.

For example, in a method of concept organization for a Panoramic Claim Charts, a meta-label sort is provided to organize concepts under meta-labels. The meta-labels are like Scope Concept groups and in one example embodiment are added by the mapper to organize map output by the groups. Additionally, the mapper is able to direct or specify the order in which the Scope Concepts are displayed, and is able to store this order or grouping for later reuse. The mapper is optionally able to hide concepts too.

In various embodiments, the mapping module 216 is also able to roll down mapping from independent claims to dependent claims. In other words, independent claim limitations, scope concepts or technology categories are treated as if they were part of dependent claims (or not, as the case may be) and optionally presented in this manner in the Panoramic Claim Chart. A dependent relationship can be established by virtue of a defined claim dependency in a given claim set, or by the mapper who may elect to define a dependency or other relationship on the fly even though such a relationship might not formally be defined in the claim set under analysis.

In various embodiments, keyword clustering may be used for improved claim mapping. This approach may be termed a “clustered” search or mapping with the mapping (or other) module 216 configured accordingly. In an example embodiment of clustered mapping the mapping module 216 and display module 212 may together be configured to display within a mapping tool (referred to as ClaimBot, for example) a user interface which includes a user interface element or mapping feature referred to as OmniMap, for example. Selection of this feature invokes a search function to find like claims. This feature requires some knowledge about what is in the subject patent portfolio and deliberate refinement of a search string that will isolate claims of like kind into a list, before the mapper makes final determination as to whether certain scope concepts apply or “map” to each claim. It is highly desirable to have the same concept mapped to many or at least several claims. Both the knowledge of portfolio content and authoring and refinement of search strings take significant time. In order to further reduce the time needed to achieve high quality maps the following is envisioned.

One or more like claims are selected as keyword ‘source claims’. The system automatically extracts keywords from the source claim(s) by considering: removing prepositions, removing other “stop” words, removing insignificant words (as defined by a dictionary), including keywords chosen in ClaimBot keyword mapping, or other criteria. The result is a set of source claim keywords.

In various embodiments, selecting a user interface element (referred to as IntelliMap, for example) a keyword search function is invoked in which the mapping module 216 is configured to search for source claim(s) keywords in the whole portfolio to speed up search and to allow multi-word keywords strings and optionally display the source claim(s) keywords in a pop-up window where the user can select relative importance of the words or groups of words (sub-clustering). The mapping module 216 searches the portfolio for occurrences of source claim keywords optionally using key-word stemming, synonym listings, pre-populated taxonomies/dictionaries, or semantic processing and returns a list of claims that is sorted by intensity of source claim keyword occunence within the claims being analyzed, or optionally weighing this occunence intensity against a determined relative importance of the source claim keywords.

This results in a mapping method as follows:

-   -   1. Choose one or more similar claims from the portfolio as         source claims.     -   2. Automatically extract keywords from the source claims.     -   3. Optionally, arrange the order of importance between extracted         keywords.     -   4. IntelliMap chosen keywords.     -   5. Optionally apply automated key-word stemming, synonym         listings, prepopulated taxonomies/dictionaries, or semantic         processing.     -   6. Search portfolio claims for keywords.     -   7. List the found claims sorted by keyword occunence intensity.     -   8. Optionally (1), revise sorting weighted against the order of         keyword importance.     -   9. Optionally (2), the mapper can further use the current search         function to refine the list of sought claims e.g. using “!”         (NOT) to exclude some claims.     -   10. The mapper can now peruse the result set for common concepts         and map them to the claims.

In various embodiments, steps 2, 4, 5, 6, 7, 8 can be fully automatic while steps 1, 3, 9, 10 initially require manual intervention but can be further automated. Automated aggregation of like claims, as per above, facilitates mapping by organizing claims in clusters of claims based on the claims' keyword content. The mapper can more easily find candidate concepts in the set of sought claims and will immediately have a claim(s) list for mapping the concepts without the need to explicitly author a search string. This method is based on the assumption that like claims to a significant degree use the same or related (e.g synonyms, stems) words.

In various embodiments, a claim similarity index is provided. A claim similarity index identifies claims to map scope concepts to. The similarity of a sub-paragraph (or element) of a claim or a full claim can be measured by: a) keyword similarity—roots of words are compared after throwing out unimportant words; b) linguistic analysis—how similar or not claim elements are based on other approaches. In one implementation, the mapping module 216 is configured to suggest to users mapping claims which claims are most similar to one another, or what parts of claims are most similar to one another. In another implementation, claims are just flagged as similar for later use.

In various embodiments, when mapping claims (for example, using the Omnimap feature mentioned above), a user is allowed to highlight the claim terms associated with a scope concept across a number of claims, storing those associations, and then when subsequently displaying those claims (for example, in the Panoramic Claim Chart) showing which claim terms have already been mapped. In various embodiments, those terms are highlighted in different colors for better visualization. This feature is helpful in situations in which a mapper moves to map another patent and has already mapped portions of claims. The highlighting makes it easier for the mapper to see what he or she has mapped. In some embodiments, the mapping module 216 is configured to automatically identify common claim terms or elements and display this in a user interface so these elements can be mapped more quickly. In some embodiments, the mapper can define common claim terms or filter them based on unique words or phrases of a certain number of words.

In some embodiments, an aid in mapping claims to a product is provided. Instead of using a claim chart, the mapping module 216 and display module 212 are configured together to show claims parsed by paragraph. Next to each paragraph, a mapper can indicate if the product includes the technology described in the claim. The same logic used in scope concept mapping is used to determine if claim is ruled out in an FTO analysis, or is novel in a validity analysis, for example.

Analytics Module

In various embodiments, analytics module 218 is to examine and run calculations on the data stored in the databases 202-210 to generate the analytics previously discussed. For example, analytics module 218 may formulate an SQL query that retrieves the number of times that a prior art reference has been cited within a portfolio. This query may be run for each prior art cited within the portfolio to determine a list of the most cited (e.g., the top ten) prior art references with a portfolio. In an embodiment, the queries are formulated and run as requested by a user. In an embodiment, once the analytics information has been determined, it is stored within analytics database 210. In various embodiments, queries are formulated and run on a periodic basis (e.g., nightly) and entries in analytics database 210 may be updated to reflect any changes. In other embodiments, the analytics module 218 may in response to user input formulate a query to examine how many times a given patent matter has been assigned or been subject to a change in ownership from one party to another. Other queries analyzing patent assignment data may be run as requested by a user.

In various embodiments, the analytics module 218 is to analyze and map cited reference data stored in the matter database 204. The data may be scraped in by the input module 214. For example, cited references owned by or cited against target or other entities as mentioned above may be mapped against each other to determine a “prior art” overlap. The overlap may be presented graphically, for example in a graphic user interface presented in user terminal 104. In various embodiments, the overlap may relate to so-called “forward” citations, or “reverse” citations, or both. In various embodiments, the overlap may be presented for a target company and one or more competitors. Changes in the overlap over time may also be stored and mapped to give an indication to a user of technology trends, changes in trends and the ongoing development of potentially relevant prior art. In various embodiments, a prior art overlap between a target and competitor may be stored, mapped and shown for a single patent, a portfolio of patents, or a family of patents. The target and other entities of interest, such as competitor companies or inventors, may be selected by the user.

An analytical result or mapping may be displayed as a list of prior art cited against both the target and competitor, with an indication of which art overlaps or is common to both listings. In various embodiments, the analytical result or mapping may in addition or alternatively present a list of companies that own the prior art cited against the target and other entities. The target company may appear as an owner. The display module 212 may be to display the results of the mappings and overlap of cited references as a bar chart, or listings, or other graphic, in a user interface of the type shown for example in FIG. 17.

In various embodiments, the analytics module 218 is to receive input identifying a pool of keywords for a first patent matter in matter database 204 and associated prior art documents in matter database 204. The term keyword is intended to include individual keywords as well as a number of keywords grouped together making up a key phrase, for example. The analytics module 218 may be further to perform a keyword analysis on the first patent matter and associated prior art documents based on occurrences of the keywords in the first patent matter and associated prior art documents. The analytics module 218 may be further to identify, based on the analysis, keywords occurring uniquely in the first patent matter. In view of their uniquely occurring nature, these keywords may be regarded as claim elements potentially differentiating the claim set or statement of invention over the disclosures contained in the one or more prior art documents.

In various embodiments, the analytics module 218 is to generate for a user the patent activity profiles of one or more entities. The entities may be competitive entities to the user, or the user's employer or client. The generated activity profiles may form part of the information to assist in strategic monitoring of patent portfolios. A patent activity profile may be built for a particular patent applicant or owner, or a type of owner, and then deviances from that profile may be flagged. The profile may include foreign filing patterns, US filing patterns—for example, analyzing whether the owner typically files a provisional application first followed by a PCT application, or whether a US application is typically filed thereafter. The profile may include information about abandonments—for example, identifying what subject matter an owner gives up or surrenders during prosecution, or in making abandonment decisions.

In various embodiments, the profile may include information about instances or circumstances in which an owner does not pay a patent annuity or renewal fee. The profile may include any of the data stored in analytics database 210 referred to above. Analytics module 218 may be to flag deviances from a profile and send update alerts to a user accordingly. For example, in conjunction with display module 212 and input module 214, analytics module 218 may present to a user an interface indicating one or more patent activity profiles for one or more patent owners for the user to select and review.

Tracking Module

The tracking module 220, according to an example embodiment, maintains information related to a specific patent, group of patents, or concept. For example, the tracking module 220 may store information related to a patent's prosecution and litigation history (such as office actions or claim amendments). In other example embodiments, the tracking module 220 may store information relating to the assignment of patent applications or patents from one assignee to another, or from an inventor to employer assignee, for example. Information of this nature may be stored by tracking module 220 for defined sets of applications or patents registered in a specified name, and within certain date ranges, for example. Update alerts (e.g., electronic mail, SMS, or similar) may be sent to a user indicating a change in ownership for a patent or patent application.

Filtering Module

In various embodiments, the filtering module 222 is to filter a set of matters according to a user preference. For example, a user may activate a check box that indicates only pending matters should be shown in a user interface. Filtering module 222 may formulate an assignment query consistent with retrieving only pending matters. The results of the query (or any query) may then be shared with display module 212 where the user interface may be updated. The regular alerts may in other example embodiments be pushed to a user terminal 104, an external website, an intranet site, a PDA, smart phone, or other similar handheld device.

The indication of the relationship may include an indication that the one or more patent claims are mapped to the patent concept.

In various embodiments, the search query includes a regular search expression, and generating the search results may include retrieving patent claims which include terms from the search query and synonyms of the terms.

Another example method embodiment is shown in FIG. 3F. A computer implemented method 300F comprises: at block 302F, maintaining a database of patent portfolios and a database of patents, each patent stored in the database of patents associated with one or more patent portfolios stored in the database of patent portfolios; at block 304F, receiving a search query associated with a first patent portfolio; at block 306F, searching the first portfolio as a function of the search query; at block 308F, generating search results, the search results including one or more patent claims associated with the search query; at block 310F, mapping the one or more patent claims to a patent concept; at block 312F, highlighting any claim terms associated with the patent scope across a number of claims; at block 314F, storing the associations; and at block 316F, displaying the highlighted claim terms to a user when subsequently displaying the one or more mapped patent claims.

Some embodiments of method 300F further include maintaining a database of ontologies, the ontologies including one or more patent concepts. The one or more patent concepts may include a technology category. The one or more patent concepts may include a scope concept, the scope concept defining a scope to which a patent claim is limited.

In some embodiments of method 300F, mapping a plurality of patent claims to a patent concept includes defining the patent concept. Mapping a plurality of patent claims to a patent concept may further include maintaining a database of patent claims, the database of patent claims including the one or more patent claims, and storing an indication of a relationship between the patent concept and the one or more patent claims in the database of patent claims. The indication of the relationship may include an indication that the one or more claims are not mapped to the patent concept. The indication of the relationship may include an indication that the one or more patent claims are mapped to the patent concept.

In some embodiments, the search query includes a regular search expression, and generating search results may include retrieving patent claims which include terms from the search query and synonyms of the terms.

For any of the methods described above, a database management system may be used (DBMS) for storing and retrieving data from a data store which includes the database of patents and database of patent portfolios. In some embodiments, the DBMS is a relational database management system (RDBMS). In some other embodiments, the data store includes storing data in a Resource Description Framework Schema (RDFS). In some embodiments, communication with the data store includes using a language such as Structured Query Language (SQL) or eXtensible Markup Language (XML).

As discussed above, an ontology may include all the metadata (patent concepts) that one may wish to map to a patent claim. For instance, the one or more patent concepts may include a technology category. The one or more patent claims may also include a scope concept, the scope concept defining a scope to which a patent claim is limited. Keywords may also be used as patent concepts. These may be any term or short phrase that appears in the claim, exactly as it appears in the claim. As these terms are taken from the claims, they may be thought of as limitations in the sense that if the term cannot be read on an accused device, the claim probably does not cover the accused device. Example user interfaces showing scope concepts in an ontology can be seen with reference to FIG. 5.

A user of the system may wish to search a previously created portfolio of patents. A patent portfolio may include patents that a user wishes to analyze. For example, a portfolio might include all of the patents for a company ABC Corp (ABC). A portfolio may be stored and defined as a patent set in the patent set database ABC might have received information on a potential infringing product. In order to find the patent claims relevant to the product, ABC may wish to map its entire patent portfolio and use the resulting mapped portfolio to quickly find the best claims to assert in an infringement lawsuit. However, it may also be useful to map the patents of the alleged infringer. These patents may also be added to the portfolio as it is likely ABC's patents and the alleged infringer's patents will have overlapping subject matter.

A search query may help to narrow down the patent. In an example embodiment, the search query many include a regular expression. For example, if the search query is “*” all the patent claims in the patent portfolio will be displayed. Boolean expressions such as “car && dog” may also be used. In some example embodiments, an option is included to only search independent claims, dependent claims, or to search both. In some example embodiments, the portfolio may further be narrowed by using patent concepts that have been included in the current ontology.

Portfolio Mapping

FIG. 4 illustrates an example user interface that may be utilized to facilitate the methods described to map patent claims, according to an example embodiment. Displayed is the title 402 of a patent portfolio, controls are also illustrated that allow a user to edit to the portfolio, list the patents in the portfolio, “quick rank,” and generate a panoramic claim map. Also shown is the “Default Ontology” 404 being used. In an example embodiment, “Quick Rank” allows a user to map all the patent claims in a patent to concepts at the same time. An ontology, in an example embodiment, includes the different concepts available to a user to map to one or more of the patent claims. Further, there is an example search criteria box 406 which allows a user to specify a search query. Included are options to narrow the search by type of claim 408 including searching independent claims, dependent claims, or both. The search expression box 410 may allow a user to specify a regular expression to use as a search query. There is also an option to have keywords highlighted 412 in the search results. In an example embodiment, this may include the searched for keywords or keywords that have previously been mapped to the claims. Also shown are options to narrow the search results by technology categories 414 and scope concepts 416.

FIG. 5 illustrates example user interfaces showing scope concepts in an ontology of the type described above with reference to the disclosed methods.

FIG. 6 shows an example user interface with example options available to search by technology category. An example option is presented allowing a user to search technology categories disjunctively or conjunctively. In an example embodiment, each technology category in the ontology is shown to the user with three example options “Direct mapped claims,” “Direct Mapped or ‘Does Not Map,’” and “Direct Mapped or ‘Unresolved.’”

FIG. 7 shows an example user interface with example options available to search by scope concept. In an example embodiment, each scope concept in the ontology is shown to the user with four example options “Direct mapped claims,” “Do not include Direct Mapped or ‘Does Not Map,’” “Direct Mapped or ‘Does Not Map,’” and “Direct Mapped and ‘Unresolved.’”

Referring back to FIGS. 3A-3F, in example embodiments a first portfolio is searched as a function of a search query and search results are generated, the search results including one or more patent claims associated with the search query. Using the search query provided, a query may be formatted as an SQL query or other suitable format to query the underlying databases. Generating the search results may include retrieving patent claims which include terms from the search query and synonyms of the terms as well as plural versions of terms in the search query.

The results of the query may then be presented to the user in an example user interface as shown in FIG. 4. Only one patent claim is illustrated, however, more patent claims may have resulted from the search and may be shown simultaneous as to have the ability to manipulate multiple patent claims. Column headings may include four radio buttons 420 signifying the options available for mapping, the matter number, the claim number, the claim text, and other technology categories or scope concepts currently mapped to the claim. Because the generated search results are searching an entire portfolio of patents it may be possible that not all of the claims of a given patent will match to the search query. A trio of numbers 422 may also be displayed for each claim in relationship to the technology category heading and the scope concept heading. These represent the nature of the relationship between the claim and the technology category or scope concept. For example, as illustrated, claim 1 has two technology categories directly mapped: “space vehicle” and “Electric Device or Method.” It also has one scope concept directly mapped.

Referring back to FIGS. 3A-3F, in example embodiments, a plurality of patent claims are mapped to a patent concept. In an example embodiment, in addition to the database of patents and patent portfolios, a database of patent claims may be maintained. The database of patent claims may be administered and interacted with using a DBMS as described above. As described above, each patent claim may have one or more patent concepts that have been mapped to the claim.

As discussed above with reference to narrowing down search results, the relationship between a patent concept and a patent claim may take on many forms. For example, the relationship may be one where the patent concept is directly mapped to a patent claim. This may indicate that a user who looked at the claim made the decision that the patent claim was in a particular technology category, for example. Another relationship may indicate that a patent concept is not mapped to a patent claim. If a user is sure that a particular claim is not in a technology category, for example, it may be beneficial for that information to be saved so that the mapping process is not unnecessarily duplicative.

With reference back to FIG. 4, a user may select one or more patent claims to map based on the radio buttons displayed. In an example embodiment, there are four radio buttons indicating options for the claim: “Direct Mapped,” “Does Not Map,” “Unresolved,” and “No Operation.” The first two options are described in detail above. The “Unresolved” radio button may indicate that a user is not sure whether the concept should be mapped to the patent claim. This may be helpful in cases where the user does not have the legal or technical expertise to make a decision one way or another. A more senior user may then review the unresolved patent claims en masse at a later time. The last radio button may indicate that a user does not wish to have any relationship defined between the patent claim and a patent concept. In an example embodiment the “No Operation” radio button is selected by default for all the patent claims returned from the search query.

Upon a user indicating a preferred mapping for each patent claim, a user may further indicate a preference of which category of patent concept to map. In an example embodiment, there are two categories: technology categories and scope concepts (e.g., elements 424 and 426 in FIG. 4). In an example embodiment, a user clicks on the button corresponding to their preference and this preference is sent to the service device which detects the category of concept the user clicked. In response, a user interface is presented to the user corresponding to his or her preference. For example, FIG. 8 may be presented.

FIG. 8 illustrates an example search box 802 and an example search results 804 section. Across the top is an option to add a new patent concept 806 (see FIG. 9 for a more detailed look at an example method to add a patent concept). Other options may include returning to the main mapping screen (e.g. FIG. 4) or canceling the mapping. In an example embodiment, the search box allows a user to search across an entire ontology for potential patent concepts. Similar to searching for patent claims, a user may enter a regular expression such as ‘*’ to retrieve all the concepts included in the present ontology. For example, the results of the search 804 displayed in FIG. 8 only returns “multiple blades.” A checkbox 808 is presented allowing a user to select the concept. If there is more than one concept displayed a user may select more than one of the concepts by selecting the respective checkboxes next to the patent concepts. A checkbox 810 at the top of the results may be selected if a user wishes to select all of the concepts returned from the ontology search.

Further example options may be presented to the right of each concept. An option to “modify and map” 812 may be selected if the user wishes to modify the concept. This may be useful if a user wishes to broaden the concept so that it may be mapped to more patent claims. For example, a narrow technology category may have been defined as “power computer speakers.” Rather than a user defining a new technology category of “passive computer speakers,” the user might decide it makes more logical sense to only have one technology category titled “computer speakers.” In an example embodiment, the user can safely select “modify and map” and change the technology category to “computer speakers.” This may safely be done because all “powered computer speakers” are also “computer speakers.” In an example embodiment, every patent claim, regardless of which portfolio(s) it may be included in, will be updated to reflect the modified concept. Thus, it may not be advisable to narrow a concept without being certain every patent claim in the system adheres to the modified concept. In an example embodiment, a warning may be displayed to the user explaining the effects of modifying a concept.

In an example embodiment, an indication of a relationship between the patent concept and the plurality of claims in the database of patents may be stored (e.g., updating one or more databases). This may be accomplished, for example, by the user selecting the map button as displayed in FIG. 8. As discussed above, a user may have selected multiple patent claims resulting from searching and may have further indicated a preference for one or more patents claims to have concepts directly mapped as well as indicated a preference to have one or more patent claims have patent concepts not mapped. Thus, in an example embodiment, the indication of the relationship may include an indication that the plurality of patent claims are not mapped to the patent concept. In an example embodiment, the indication of the relationship includes an indication that the plurality of patent claims are mapped to the patent concept.

In some example embodiments mapping a plurality of patent claims to a patent concept includes defining the patent concept. Defining the patent concept may be initiated by a user clicking on the example “add_new” button 806 as displayed in FIG. 8. An example user interface that may be presented to the user in response to this selection is illustrated in FIG. 9. Two example options may be presented, “Save” and “Cancel.” Also shown are two input text boxes, “Concept Name” and “Description.” The concept name may be the actual concept and may be, for example, either a technology category or a scope concept. A user may indicate which category of patent concept the new concept belongs using a pull down menu. The user may further wish to add the concept to an existing ontology by selecting one or more ontologies as presented in FIG. 9.

Report and Chart Generation

As described above, the system may allow the generation of visual representation of the data included in the databases to further maximize the value of concepts to patent claims. In some example embodiments, the visual representation may be in the form of charts sometimes called Panoramic Claim Charts which may be interactive. In some example embodiments, a method to generate the charts includes formulating a query to send to one or more databases, the query requesting whether or not a set of patent claims have been mapped to a set of patent concepts. An additional query may be sent to the databases to determine additional metadata about the patent claims including, but not limited to, the filing data and owner of each patent. Ranking data may be received for each patent concept retrieved from the databases. In an example embodiment, the system generates a relationship between a ranking, a patent concept, and a patent claim and displays the relationship to the user in the form of a chart. The ranking data may be stored in the database or may be received from a user. In some embodiments, ranking data may include integer values of disparate range (e.g., 1-10 or 1-100) alphabetical letters (e.g., a grading scale of A-F), or any other means to characterize a claim or concept.

In an example embodiment, a competitor landscape chart may be generated. An example simple competitor landscape chart is shown in FIG. 10. Shown is the title, patent number, filing data, total claims, each independent claim, and owner of each patent in a patent set. The patent set may reflect the patents owned by the competitors of a company requesting the map. The scope concepts that have been mapped to the patent claims in the patent set may be displayed as rows in the chart. If a scope concept has been mapped to a patent claim than the intersecting cell between the patent claim and concept may be filled in, checked, change color, patterned, shaded or otherwise have an indication of the mapping. Additional columns may indicate the competitor that first introduced a concept as well as the date it was introduced. This may be determined by examining each patent that has a concept mapped to at least one of the claims and examining the dates of each of the matching patents. In addition, the scope concepts may be sorted by frequency. Each competitor may be assigned a color or other designation such that a user may quickly determine which company owns each patent as well as who introduced what concepts first.

In an example embodiment, a product coverage chart may be generated. An example product coverage chart is shown in FIG. 11. As with FIG. 10, relevant patent information for patents included in the patent set is displayed. Also, displayed is a column titled “Has Feature?” This column may have values ranging from one to three signifying the degree to which the product includes the concept. For example, a value of three may mean the product definitely includes the concept and a value of one means the product definitely does not relate to the concept. Based on these values, the chart may dynamically update and determine values for the claim coverage and product coverage rows. For example, SC 1 and SC 5 both have a rating of ‘3’ and are present in all of the claims of patent “Title 1.” Thus, “Title 1” has a claim coverage of ‘3’ and a product coverage value of “potentially applies.” It is only “potentially applies” because it cannot be known for certain whether the patent applies but only that that SC 1 and SC 5 are present in the claims. However, because scope concepts always describe limitations, if a claim has two scope concepts mapped, as shown with respect to the claims in patent “Title 2,” the lowest ratings score will control the claim coverage. As shown, SC 6 is described as not being present in the product and the “Title 2” claims have been mapped to SC 6. Therefore, regardless of the fact the SC 3 has also been mapped and the product has this feature, the “Title 2” claims cannot apply to the product as they are at least limited to SC 6.

This chart may also allow interactivity with a user. This interactivity may include the user changing the “Has feature” values and the chart automatically updating the claim coverage and product coverage rows. For example, if the SC 1 rating was changed to ‘1,’ the claim coverage value of the patent “Title 1” may change to “1” signifying the patent does not apply to the product. In some embodiments, any changes that result from input from the user are highlighted on the chart. This may allow a user to quickly see the effects of potential changes to product coverage.

FIG. 12 illustrates an example freedom to operate chart. In an example embodiment, a freedom to operate chart allows a user to quickly see which patents may be necessary to obtain licenses from or purchase to produce a product, sell a service, etc. FIG. 12 is similar to FIG. 11 except for in place of a “Has feature?” column there is a “Need Feature?” column. The values in this column may represent whether or not, and to what extent, a user believes a feature is necessary in his or her product. A ‘3’ may indicate that the scope concept is necessary, a ‘2’ may indicate the scope concept is wanted, but not needed, and a ‘1’ may indicate the scope concept is not needed. In an example embodiment, the “claim status” row shown in FIG. 12 reflects whether a patent in the patent set needs to be licensed or purchased in order for the user to operate freely. As with the product coverage chart, the lowest value in the “need feature” column controls. Thus, patent “Title 1” is not needed even though SC 1 is mapped to all the claims and the user has indicated the feature is necessary. Similarly to above, a user may interact with the ratings to see in real-time the impact of removing or adding features in terms of the number of patents needing to be licensed or purchased.

FIG. 13 illustrates an example claim/patent valuation chart. In an example embodiment, a claim/patent valuation chart allows a user to see which patents/claims may be necessary to license, etc., to maximize the value of a currently owned patent or patent claim. FIG. 13 is similar to FIG. 11 except the values in the ratings column reflect whether or not a scope concept is necessary to maximize a patent's value. The values in this column may represent whether or not, and to what extent, a user believes a feature is necessary in maximize a patent's value. A ‘3’ may indicate that the scope concept is necessary, a ‘2’ may indicate the scope concept is wanted, but not needed, and a ‘1’ may indicate the scope concept is not needed. In an example embodiment, the “claim value” row shown in FIG. 13 reflects whether a patent in the patent set needs to be licensed or purchased in order to maximize the user's patent. As with the product coverage chart, the lowest value in the rating column controls. Thus, patent “Title 1” is not important, even though SC 1 is mapped to all the claims and the user has indicated a high value for SC 1. Similarly to the above charts, a user may interact with the chart by changing the ratings to see in real-time the effects on patents in the patent set.

FIG. 14 illustrates an example validity chart. In an example embodiment, a validity chart allows a user to see the overlap between a patent and a patent set. FIG. 14 is similar to FIG. 11 except the values in the ratings column reflect whether or not a feature is shown in the patent in question (the patent to which the patent set is being compared). The values in this column may represent whether or not, and to what extent, a user believes a feature is present in the patent in question. A ‘3’ may indicate that the scope concept is shown, a ‘2’ may indicate the scope concept is possibly shown, and a ‘1’ may indicate the scope concept is not shown. In an example embodiment, the claim status row shown in FIG. 14 reflects the extent to which the patent in question and the patents in the patent set overlap. Unlike the product coverage chart, if two scope concepts are mapped to a patent, but contain different ratings, the feature rating becomes “some overlap”. Thus, even though SC 5 has been rated as not shown and mapped to patent “Title 1,” SC 1 is also mapped to the patent but is shown and therefore there is some overlap between the patent in question and patent “Title 1.” A finding of “complete overlap” may indicate to a user that a patent or claim is completed anticipated. As above, the user may interact with the chart by changing the ratings to see in real-time the effects on patents in the patent set.

FIG. 15 illustrates an example white space analysis chart. In an example embodiment, a white space analysis chart allows a user to see the frequency in which scope concepts appear in a patent set. In some embodiments there are scope concepts that are in no patent claims. The chart may be color coded to allow a user to quickly ascertain the least frequently used scope concepts. FIG. 16 illustrates an example white space claim generation chart. In an example embodiment the generated chart illustrates suggested combinations of unclaimed combinations of existing scope concepts as well as suggested combinations of new scope concepts with existing scope concepts.

Reference is now made to FIG. 17 which shows a user interface 400 that may be used to facilitate further mapping methods of the present inventive subject matter, according to example embodiments. The user interface 1700 may be displayed by display module 212 described above. The user interface 1700 may be provided in a website, computer monitor, or mobile device. The type of user elements, names, and layout depicted in FIG. 17 are intended to be an illustration of an example user interface of patent management system 102. Other types of user elements, names, and layouts may be used.

User interface 1700 is illustrated with multiple user interface elements. In an example embodiment, a user interface element is a graphical or textual element that a user may interact with to cause an application to perform an assigned action for the interface element. Data representing user interface 1700 may be transmitted via network 106 and presented on a display of user terminal 104 through the use of a web browser. A user (e.g., manager of a patent portfolio, etc.) may interact with the user interface elements of user interface 1700 through the use of an input device (e.g., stylus, cursor, mouse, a finger) of the user terminal 104. In an embodiment, a user selection is based on the coordinates of the input device as it makes contact with the display or where a user “clicks” the mouse. The coordinates are compared to the coordinates of the user input element to determine the selection. The type of user elements, names, and layout depicted in FIG. 17 are intended to be an illustration of an example user interface of patent management system 102. Other types of user elements, names, and layouts may be used. Some elements may be omitted in various embodiments depending on the nature of management tool provided.

In general, the user interface elements may include my matters 1702, patent watches 1704, and company watches 1706. These elements may be used to select a context/view of the patent management system 102. For example, my matters 1702 lists the patents included within a portfolio of a user, patent watches 1704 lists information on patents that the user has indicated the patent management system 102 is to watch, and company watches 1706 lists information on companies that the user has indicated the system 102 should watch.

In various embodiments, a prior art overlap mapping tool includes further user interface elements which allow a user to input, for example at element 1708, the identity of a target entity and the identity of at least one other entity of interest. This input may be passed to the input module 214 for searching. The target entity might be an inventor of interest or a client, for example, while the at least one other entity of interest might be one or more competitors, for example. The input module 214, for example, is to search for and identify prior art cited against the patent filings (optionally domestic, foreign or both types of filings) of the identified target and competitor entities, and the display module 212 is to display the references in a window 1710, for example.

In display windows 1712, 1714, and 1716, the references may be broken down into listings of references cited against the target and the selected competitors. The references may be aggregated together, or in various embodiments, further broken down into group listings relating to one or more patents, patent matters or patent portfolios, or in various embodiments, into groupings relating to one or more domestic or foreign countries.

In various embodiments, further data relating to the cited references is provided. In windows 1718 and 1720, specific data relating to one or more cited references is provided. For example, the name of the owner of Reference A is shown at window 1722 as “x”. Any instances of reverse or back citations of Reference A are shown at window 1724, and instances of forward citations of Reference A at window 1726, for example. Similar details for Reference B may be shown at windows 1728, 1730 and 1732, for example.

The cited references found for the target and other entities can be conveniently displayed in a bar chart or other graphic. In an example embodiment, numeral 1734 indicates a chart having three bar lines. Each bar line represents the citation listings for a target entity and two competitors A and B identified by a user. Details of each citation listed in a bar line may be given, but are not shown here in the interests of clarity. A representation of the prior art overlap can be shown and is here illustrated by arrow 1736 which indicates a zone of commonality of references found for each of the target and competitors A and B. Other zones of commonality, such as indicated by arrow 1738, listing references common to the target and competitor A only, can be given. At a quick glance, a user can determine which areas of art or technology are being cited against or developed by each entity. In various embodiments, the zone of commonality can be rechecked at various intervals so that ongoing trends in the art can be analyzed over time.

Modules, Components and Logic

Certain embodiments are described herein as including logic or a number of components, modules, or mechanisms. Modules may constitute either software modules (e.g., code embodied (1) on a non-transitory machine-readable medium or (2) in a transmission signal) or hardware-implemented modules. A hardware-implemented module is tangible unit capable of performing certain operations and may be configured or arranged in a certain manner. In example embodiments, one or more computer systems (e.g., a standalone, client or server computer system) or one or more processors may be configured by software (e.g., an application or application portion) as a hardware-implemented module that operates to perform certain operations as described herein.

In various embodiments, a hardware-implemented module may be implemented mechanically or electronically. For example, a hardware-implemented module may comprise dedicated circuitry or logic that is permanently configured (e.g., as a special-purpose processor, such as a field programmable gate array (FPGA) or an application-specific integrated circuit (ASIC)) to perform certain operations. A hardware-implemented module may also comprise programmable logic or circuitry (e.g., as encompassed within a general-purpose processor or other programmable processor) that is temporarily configured by software to perform certain operations. It will be appreciated that the decision to implement a hardware-implemented module mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations.

Accordingly, the term “hardware-implemented module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired) or temporarily or transitorily configured (e.g., programmed) to operate in a certain manner and/or to perform certain operations described herein. Considering embodiments in which hardware-implemented modules are temporarily configured (e.g., programmed), each of the hardware-implemented modules need not be configured or instantiated at any one instance in time. For example, where the hardware-implemented modules comprise a general-purpose processor configured using software, the general-purpose processor may be configured as respective different hardware-implemented modules at different times. Software may accordingly configure a processor, for example, to constitute a particular hardware-implemented module at one instance of time and to constitute a different hardware-implemented module at a different instance of time.

Hardware-implemented modules can provide information to, and receive information from, other hardware-implemented modules. Accordingly, the described hardware-implemented modules may be regarded as being communicatively coupled. Where multiple of such hardware-implemented modules exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) that connect the hardware-implemented modules. In embodiments in which multiple hardware-implemented modules are configured or instantiated at different times, communications between such hardware-implemented modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware-implemented modules have access. For example, one hardware-implemented module may perform an operation, and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware-implemented module may then, at a later time, access the memory device to retrieve and process the stored output. Hardware-implemented modules may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information).

The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented modules that operate to perform one or more operations or functions. The modules referred to herein may, in some example embodiments, comprise processor-implemented modules.

Similarly, the methods described herein may be at least partially processor-implemented. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented modules. The performance of certain of the operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processor or processors may be located in a single location (e.g., within a home environment, an office environment or as a server farm), while in other embodiments the processors may be distributed across a number of locations.

The one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., Application Program Interfaces (APIs).)

Electronic Apparatus and System

Example embodiments may be implemented in digital electronic circuitry, or in computer hardware, firmware, software, or in combinations of them. Example embodiments may be implemented using a computer program product, e.g., a computer program tangibly embodied in an information carrier, e.g., in a machine-readable medium for execution by, or to control the operation of, data processing apparatus, e.g., a programmable processor, a computer, or multiple computers.

A computer program can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, subroutine, or other unit suitable for use in a computing environment. A computer program can be deployed to be executed on one computer or on multiple computers at one site or distributed across multiple sites and interconnected by a communication network.

In example embodiments, operations may be performed by one or more programmable processors executing a computer program to perform functions by operating on input data and generating output. Method operations can also be performed by, and apparatus of example embodiments may be implemented as, special purpose logic circuitry, e.g., a FPGA or an ASIC.

The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. In embodiments deploying a programmable computing system, it will be appreciated that both hardware and software architectures usually require consideration. Specifically, it will be appreciated that the choice of whether to implement certain functionality in permanently configured hardware (e.g., an ASIC), in temporarily configured hardware (e.g., a combination of software and a programmable processor), or a combination of permanently and temporarily configured hardware may be a design choice. Below are set out hardware (e.g., machine) and software architectures that may be deployed, in various example embodiments.

Example Machine Architecture and Machine-Readable Medium

FIG. 18 is a block diagram of machine in the example form of a computer system 1800 within which instructions for causing the machine to perform any one or more of the methodologies discussed herein may be executed. In alternative embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client machine in server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine may be a personal computer (PC), a tablet PC, a set-top box (STB), a PDA, a cellular telephone, a web appliance, a network router, switch or bridge, or any machine capable of executing instructions (sequential or otherwise) that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein.

The example computer system 1800 includes a processor 1802 (e.g., a central processing unit (CPU), a graphics processing unit (GPU) or both), a main memory 1804 and a static memory 1806, which communicate with each other via a bus 1808. The computer system 1800 may further include a video display unit 1810 (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)). The computer system 1800 also includes an alphanumeric input device 1812 (e.g., a keyboard), a user interface (UI) navigation or cursor control device 1814 (e.g., a mouse), a disk drive unit 1816, a signal generation device 1818 (e.g., a speaker) and a network interface device 1820.

Machine-Readable Medium

The disk drive unit 1816 includes a machine-readable medium 1822 on which is stored one or more sets of data structures and instructions 1824 (e.g., software) embodying or utilized by any one or more of the methodologies or functions described herein. The instructions 1824 may also reside, completely or at least partially, within the main memory 1804 and/or within the processor 1802 during execution thereof by the computer system 1800, with the main memory 1804 and the processor 1802 also constituting machine-readable media.

While the machine-readable medium 1822 is shown in an example embodiment to be a single medium, the term “machine-readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more data structures or instructions 1824. The term “machine-readable medium” shall also be taken to include any tangible medium that is capable of storing, encoding or carrying instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the embodiments of the present invention, or that is capable of storing, encoding or carrying data structures utilized by or associated with such instructions. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories, and optical and magnetic media. Specific examples of machine-readable media include non-volatile memory, including by way of example semiconductor memory devices, e.g., Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.

Transmission Medium

The instructions 1824 may further be transmitted or received over a communications network 1826 using a transmission medium. The instructions 1824 may be transmitted using the network interface device 1820 and any one of a number of well-known transfer protocols (e.g., HTTP). Examples of communication networks include a local area network (“LAN”), a wide area network (“WAN”), the Internet, mobile telephone networks, Plain Old Telephone (POTS) networks, and wireless data networks (e.g., WiFi and WiMax networks). The term “transmission medium” shall be taken to include any intangible medium that is capable of storing, encoding or carrying instructions for execution by the machine, and includes digital or analog communications signals or other intangible media to facilitate communication of such software.
